SLO-4G63

Alright....now I know that the box for the profec that mounts under the hood has an in and an out now the in if I am correct should pull it's reading from the compressor housing for the turbo.....as well as the reading from the waste gate....the of course the out line coming off the box would go to the back of the module inside the car. If I am correct then my next question is where would be a safe place to tap into a 12v line when the ignition is turned on. I already tapped into the ecu for my shift light and really don't want to be running too much crap off of that same one.....so im thinking that the switchable 12v power for the turbo timer would be my 2nd best choice. Any insight on this would be greatly appreciated.

The one from your TT will work, or the one from cigarette lighter. There's also a switched line off the ignition switch and one at the radio.
